Speakers are often thought of as hard and rectangular, but Ultimate Ears' UE Roll portable speakers challenge both of these features. Rather than adopting these two qualities, the speakers are encased in a plasma-coated life-proof case that promises to be resistant to water and dirt. The round shape of the shell makes it possible to enjoy music from all angles, ideal for toting on all of your summer adventures.

Although the UE Roll's size makes it portable enough, this feature is enhanced with the inclusion of a marine-grade bungee cord, which makes it possible to attach the speaker to virtually anything. To amplify the sounds that can come from this device, it can even be combined with other UE speakers.

As mobile devices and accessories are becoming more capable and durable, consumers are expecting that portable speakers will be able to keep up.
